Subsequently, the rail 2 of the pre-branching conveying path 400 is connected to the connecting rail 8, the connecting rail 8 is connected to the rail 2 b, and the rail 2 b is connected to the rail 2 d. Therefore, a shape is achieved in which the rail 2, the connecting rail 8, the rail 2 b, and the rail 2 d are mutually connected in a line.
In a case where one end of the rail 2 a is connected to the connecting rail 8 and the other end of the rail 2 a is connected to the rail 2 c as illustrated in FIG. 4 , the conveying carriage that has entered from the pre-branching conveying path 400 to the conveying-path rotary switching unit 200 is driven by the stators 1 while being supported by the rail 2 a in the conveying-path rotary switching unit 200. A track shape formed by centers of end surfaces of the stators 1 on the side of the rail 2 a is designed to be coincident with the rail 2 a so that the conveying carriage on the rail 2 a can be driven.
In a case where one end of the rail 2 b is connected to the connecting rail 8 and the other end of the rail 2 b is connected to the rail 2 d as illustrated in FIG. 5, the conveying carriage that has entered from the pre-branching conveying path 400 to the conveying-path rotary switching unit 200 is driven by the stators 1 while being supported by the rail 2 b in the conveying-path rotary switching unit 200 as in the case in FIG. 4 . A track shape formed by centers of end surfaces of the stators 1 on the side of the rail 2 b is designed to be coincident with the rail 2 b so that the conveying carriage on the rail 2 b can be driven.
In the conventional technique, it is necessary to provide stators the number of which corresponds to the number of conveying paths for branching. Meanwhile, according to the first embodiment, the conveying carriage is driven, on both the rail 2 a and the rail 2 b, by the same stators 1 that penetrate through the conveying-path rotary switching unit 200 as illustrated in FIGS. 4 and 5 . Therefore, the same stators 1 can be used both before and after switching of the conveying-path rotary switching unit 200. Consequently, the number of components, more specifically, the number of provided stators can be reduced as compared with that in the conventional technique.
Although a cuboid has been exemplified as the shape of the conveying-path rotary switching unit 200 in the first embodiment, the present invention is not limited thereto. The shape of the conveying-path rotary switching unit 200 is not limited to a cuboid, as long as the stators 1 can be used in a shared manner for both the first conveying path 101 and the second conveying path 102 that can be switched by rotation.
Further, although a mode in which the first conveying path 101 and the second conveying path 102 through which the stators 1 penetrate are opposite surfaces to each other has been exemplified in the first embodiment, the present invention is not limited thereto. It is not always necessary that the first conveying path 101 and the second conveying path 102 are provided on the opposite surfaces to each other, as long as both the first conveying path 101 and the second conveying path 102 that can be switched by rotation can share the stators 1 penetrating the first conveying path 101 and the second conveying path 102. In a case where two surfaces are opposite surfaces, when one of the surfaces is assumed as a front surface, the other is a back surface and an angle formed by normal vectors of these surfaces is 180 degrees.
Furthermore, although the stators 1 penetrate two track surfaces in the first embodiment, the present invention is not limited thereto. The conveying-path rotary switching unit 200 may include a further track surface other than the first conveying path 101 and the second conveying path 102, as long as all the track surfaces that can be switched by rotation can share the stators 1 penetrating these track surfaces.
Further, although the rotation axis 20 of the conveying-path rotary switching unit 200 is parallel to the traveling direction in the first embodiment, the present invention is not limited thereto. It suffices that track surfaces for a conveying carriage are switched by rotation and all the track surfaces that can be mutually switched share the stators 1 penetrating the track surfaces, and it is not always necessary that the rotation direction is parallel to the traveling direction.
In a case where the stators 1 are electromagnets in the first embodiment, it is necessary to lead a power cable. Further, because it is necessary to provide a position detector for a conveying carriage in the conveying-path rotary switching unit 200, an output cable of the position detector needs to be led. In a case where it is necessary to lead the cable that connects the conveying-path rotary switching unit 200 and outside to each other as described above, it suffices that a portion from the shaft 3 a to the shaft 3 b, which are to rotate, is formed to be hollow and the cable is led through the hollow shafts 3 a and 3 b to outside of the conveying-path rotary switching unit 200. That is, it suffices that a wiring hole is provided along the rotation axis 20. According to this configuration, it is possible to suppress a relative behavior of the cable with respect to the conveying-path rotary switching unit 200, caused by rotation of the conveying-path rotary switching unit 200, and to suppress disconnection of the cable. It suffices that the cabling hole is provided along the rotation axis 20 of the conveying-path rotary switching unit 200, and the hole may be another means. For example, a solid shaft may be provided at the position of the shaft 3 a or the shaft 3 b to cantilever-support the conveying-path rotary switching unit 200, and the wiring hole may be provided along the rotation axis 20 of the conveying-path rotary switching unit 200 in a different surface from a surface on which the solid shaft is provided.
As described above, according to the first embodiment, the stators 1 penetrate a plurality of track surfaces of the conveying-path rotary switching unit 200 and the stators 1 can be shared by the track surfaces. Therefore, the number of the provided stators 1 can be reduced.
In a second embodiment, a mode is described in which tracks of conveying paths for branching, formed by center points of end surfaces of stators on the conveying-paths, are symmetric with respect to a plane that passes through a rotation axis of a conveying-path rotary switching unit.
Because the track 10 a and the track 10 b are symmetric with respect the virtual plane 30 that passes through the rotation axis 20, the stators 1A penetrate through the base 200 aA in the shortest route. Further, it is preferable that a stator is formed in the form of a cylinder having a bottom surface that is in contact with a conveying surface, in general. However, it is possible to form each stator 1A in the form of not only a cylinder but also a frustum with respect to the conveying surface. In a case where the stators 1A are formed in the form of cylinders or frustums, the stators 1A can have the same shape as each other and it is therefore possible to manufacture the stators 1A with less workload. Further, when the stators 1A are formed in the form of cylinders or frustums in a case where the stators 1A are coils, it is easy to wind the coils parallel to the conveying surface, and winding design and winding work are easy.
According to the second embodiment, it is possible to reduce a process of manufacturing stators.
In a third embodiment, a mode achieving such a shape that a curvature of a track is continuous is described. In the third embodiment, constituent elements identical to those illustrated in the first and second embodiments are denoted by like reference signs and explanations thereof are omitted. Explanations of the first and second embodiments are incorporated herein.
The conveying carriage 600 travels from the rail 2 to the rail 2 c via the connecting rail 8 and a rail 2 aB. The shape of a track 10 aB for the conveying carriage 600 is such a shape that a curvature is continuous from the rail 2 to the rail 2 c via the connecting rail 8 and the rail 2 aB.
A centrifugal force F acting on the rail 2 aB is calculated here. Using a curvature ρ of the rail 2 aB, a velocity V of the conveying carriage 600, and a mass M of the conveying carriage 600, F=M×ρ×V2 is established. From this expression, the centrifugal force F is linear with respect to the curvature p. Therefore, the centrifugal force F is discontinuous if the curvature ρ is discontinuous, which causes generation of an impact on the conveying carriage 600. As a result, there is a risk that the conveying carriage 600 or a conveyed object on the conveying carriage 600 is damaged.
Therefore, the track 10 aB is formed to have such a shape that the curvature is continuous from the rail 2 to the rail 2 c via the connecting rail 8 and the rail 2 aB as illustrated in FIG. 7 . With this configuration, it is possible to reduce generation of an impact on the conveying carriage 600.
According to the third embodiment, it is possible to reduce an impact on the conveying carriage 600 and to reduce damage of the conveying carriage 600 and a conveyed object on the conveying carriage 600.
The third embodiment can be combined with the first and second embodiments.
In a fourth embodiment, a mode is described in which any of the conveying path switching devices described in the first to third embodiments is applied as a hoistway switching device of an elevator apparatus.
As is well known, a conventional elevator apparatus is configured in such a manner that a car and a counterweight are provided in a hoistway, are coupled to each other with a main rope, and are driven to be raised and lowered by a hoisting motor installed in a machine room.
Meanwhile, a rope-less elevator apparatus is known which drives a car by thrust generated between a primary coil of a linear motor provided in a hoistway and a permanent magnet that is provided in the car and configures a secondary side of the linear motor.
Further, an elevator apparatus capable of moving both vertically and horizontally is also known which can move not only in a single hoistway but also to a different hoistway. In this elevator apparatus capable of moving both vertically and horizontally, a car is moved horizontally to switch hoistways.
In the state illustrated in FIG. 8 , the conveying carriage 600 that has entered a hoistway switching device 200C from a pre-branching hoistway 810 is driven by the stators 1 while being supported by the rail 2 a in the hoistway switching device 200C. A shape of a track formed by centers of end surfaces of the stators 1 on the side of the rail 2 a is designed to be coincident with the rail 2 a so that the conveying carriage 600 on the rail 2 a can be driven. As a result of this configuration, it is possible to cause the conveying carriage 600 to enter a first post-branching hoistway 820 a.
Further, although not illustrated, it is possible to cause the conveying carriage 600 to enter a second post-branching hoistway 820 b by switching a conveying path in a rotating manner as in FIG. 5 of the first embodiment.
Next, advantageous effects of the fourth embodiment are described. In the above-described conventional elevator capable of moving both vertically and horizontally, it is necessary to stop a car once in order to move it to a different hoistway. On the other hand, in a case of the hoistway switching device 200C according to the fourth embodiment, it is unnecessary to stop the car when the car moves to the different hoistway. Further, it is possible to reduce the number of components, more specifically, the number of provided stators, as compared with a case where the technique of Patent Literature 1 described as a prior art document of the present application is applied to the conventional elevator capable of moving both vertically and horizontally as it is.
While the conveying carriage 600 travels on the first conveying path 101 and the second conveying path 102 that are hoistways for branching, it is necessary that the posture of a car, on which a passenger or a cargo is to be loaded, with respect to the ground is constant. Therefore, the car 800 is provided via the rotary joint 700 as illustrated in FIG. 8 , so that the posture of the car 800 with respect to the ground is kept constant. In a case where the posture of the car 800 with respect to the ground is not stable because of friction with a contact portion of the rotary joint 700 or the like, it suffices to solve this problem by employing a configuration in which a rotary actuator and its control device are added or providing a mechanical locking mechanism to keep the posture of the car 800 with respect to the ground constant, for example.
The configurations described in the above embodiments are only examples of the content of the present invention. The configurations can be combined with other well-known techniques, and part of each of the configurations can be omitted or modified without departing from the scope of the present invention.
